Fix incorrect use of EV_SET on pipes (part 2) 
Forgot that we use nearly the same routine for adding and deletion...
can't go around deleting things we haven't put into the changeset!

Fix incorrect use of EV_SET on pipes. 
It would seem adding a read and a write event filter on a pipe which is
unidirectional might just be a bad idea.

Disabling superfluous code 
The code in question may be checking things in an erroneous manner?

Better exit (error?) message 
The prior calls to exit(-1) were wrong anyway and they may at this point
be hindering figuring out what's going on in suite 9.

Add kqueue support to Janet 
Note that this is a work in progress and simply a first attempt at
getting some code into place before being able to test it. This code
follows of sorts both the poll and epoll sections of the codebase hoping
to achieve the exact same.

Calvin Rose 7037532943 Errored threads always emit stacktrace or supervisor event. 
That way, it is much harder to swallow errors. Error swallowing behavior
would have to be done explicitly by wrapping fibers with `protect` or
`try`.

Calvin Rose ef23356309 Threaded supervisors return fiber->last_value instead 
of the fiber itself.

Calvin Rose 5464a7a379 Allow passing a function to directly to ev/go. 
Makes ev/call less useful but ev/go more useful. No need
to construct as many identical intermediate fibers.
 2021-08-30 22:22:22 -05:00
Calvin Rose acbebc5631 Allow passing function to ev/thread. 
Convenient when there is no need to create an entire fiber.

Calvin Rose c8827424e7 Fix memory leak and use after free 
Use after free was caused by missing janet_gcroot call when
setting up thread.

Calvin Rose cc066dd6a1 Add basic runtime support for threaded abstracts. 
A threaded abstract is an abstract type that can be freely shared
between threads. While no synchronization is provided, refcounting
and transport between threads is. This will let implementers more easily
exploit OS-level parallelism in C library code. The caveat with these
types is that they need to be careful in how they interact with objects
on other heaps.

Calvin Rose e552757edc Fix threaded supervisor channels - Fix #766 
Some pointer casting with abstract types was incorrect, resulting
in strange behavior when trying to use supervisor channels that were
threaded. This fix also adds the ability to supply a supervisor channel
directly when creating a thread.

Calvin Rose b75b3e3984 Working example for threaded channels. 
Still no marshalling more complex values.

Calvin Rose 97e5117a3f Fix some issues and improve channel closing. 
Still not fully working, seems to be deadlock/channel issue when
sending events between threads.
 2021-08-15 13:14:33 -05:00
Calvin Rose 037215f7c4 Initial working draft of threaded channels. 
Introduces close semtantics to channels as well, but otherwise
threaded channels behave much like non-threaded channels. They have
different marshalling behavior though, and can only send values over by
packing and unpacking them. For now, this means only primitive values
although this will be expanded.

Also missing some implementation for closing threaded channels, and a
whole lot of testing. Achtung!, Caveat emptor, here be dragons and bugs.
 2021-08-15 11:48:13 -05:00
Calvin Rose e76b8da269 Add semantics for closing channels. 
This makes certain algorithms simpler as channels
now have an explicit lifetime - multiple readers can coordinate
closing without needing to ensure the same number of reads as writes.

bakpakin 6f1695ecd4 Add utitities for interrupting the event loop. 
janet_loop1_interrupt makes the event loop compatible
with safe interruptions for custom scheduling. Does this by exposing
custom events on the event loop. A custom event schedules a function pointer
to run in a way that can interrupt
epoll_wait/poll/GetQueuedCompletionStatus.

Calvin Rose e7ea39f410 Prevent possible bad garbage collection when finalizing streams.

themselves.
